The speed charts following the first day of testing look much like the race results from last year’s 50th Anniversary Rolex 24 At Daytona.

Fastest of the day in the Rolex Series was the defending race champion No. 60 Michael Shank Racing Ford Riley with AJ Allmendinger, who turned a lap of 124.526 mph.

“As soon as I got in it, the first couple of laps, I was like this thing feels pretty good,” said Allmendinger, who along with Ozz Negri, Justin Wilson and John Pew captured the 50th Anniversary Rolex 24 At Daytona. “Obviously conditions are going to change and you’re going to have to stay up with the race track but when you can go out there right away and be fast and not even push the car too hard is a good feeling.

“Coming in here, you see everybody’s faces, Michael Shank especially and the crew guys. It’s exciting to come back and be defending champions but it also inspires us to go do it again because we know what it was like to be in (Gatorade) Victory Lane and what that feeling was and to be able to celebrate with each other.”

Last year’s GT class champions in the Rolex 24 – Magnus Racing – was fastest in class on Friday with the No. 44 Porsche GT3 Cup and driver Andy Lally, who posted a speed of 117.232 mph.

In the newly formed GX class, the No. 16 Napleton Racing Porsche Cayman with David Donohue was fastest with a lap of 109.104 mph.

Rules for 2014: During the lunch break of Friday’s test, GRAND-AM Road Racing and the American Le Mans Series presented by Tequila Patrón unveiled the initial concept for the organizations’ unified competition class structure that will debut in January 2014 at the 52nd Anniversary of the Rolex 24 At Daytona.

The lineup – in effect for the 2014 and 2015 seasons – is based on a philosophy of inclusion. The majority of classes from both the GRAND-AM Rolex Sports Car Series and the ALMS will be retained with the exception of the ALMS’ P1 prototype class

Individual class names have yet to be determined. The planned structure:

GRAND-AM’s DP and the ALMS’ P2 classes will combine into one, headlining prototype class that also will include the revolutionary DeltaWing prototype, with performance of the cars balanced to maintain close competition.

The ALMS’ Prototype Challenge (PC) class for spec prototypes will continue to run as a separate class.

Both of the organizations’ production-based GT classes will continue as separate, distinct categories based on performance, preserving each class’ proud history and loyal fan following. As part of this plan, the ALMS’ GTC cars will join the GRAND-AM GTs.

GRAND-AM’s new GX class, which is debuting at this year’s Rolex 24 later this month, is being explored as a possible addition to the GRAND-AM half of the GT mix in 2014-15. There also is the possibility that GX will run separately as a fifth class.

Specifications for all classes still are being determined and will be announced later this year. In addition, there will be continued discussion regarding the increasing inclusion of green technologies in the new unified series.

Scout Days: During this weekend’s Roar Before The Rolex 24, more than 2,600 Boy and Girl Scouts from throughout the state of Florida will be participating in Scout Days.

The Scouts will camp overnight on Friday and Saturday night in the infield in Turns 3 and 4 as well as participate in garage tours, scavenger hunts, tech talks and pit stop demonstrations.
